Book's exploration of pregnancy advice stirs controversy

In her book "Expecting Better," health economist Emily Oster attempts to shed light on the science behind common advice for pregnant women, although experts have questioned some of her conclusions. Oster was inspired to research and write the book after her own pregnancy, during which she says she received advice without much explanation. Dr. Jeffrey L. Ecker suggests an important lesson for clinicians from the book is the reminder that expectant women seek a "shared decision-making model" with their health care providers.
